Core Lithium is one of very few lithium developers globally that are ready to start new project construction in 2021 to take advantage of high spodumene prices.

Significantly, Core notes that yesterday, a spodumene concentrate cargo from another Australian producer sold for an approximate equivalent price of USD$2,500/dmt (SC6.0, CIF China). Core is the only Australia-focused, ASX-listed company forecast to join the ranks of new spodumene producers between now and the end of 2022.

Core has recently financed the Finniss Lithium Project and is preparing to make a Final Investment Decision in coming weeks ahead of starting construction on the Project before the end of this year and targeting first production in late 2022.

The Company is not aware of any other specific information that may explain the recent trading in its securities.
